A strong hub-centric wheel spacer matches the vehicle’s bolt pattern and hub bore, then provides the thickness and hardware your wheel setup requires. KSP 6×5.5 Silverado Spacers suit shoppers seeking a forged 1.5-inch set for compatible Silverado and Sierra models, while this roundup also covers thinner options and other fitments. The products vary substantially: listed thicknesses range from 12mm to 2 inches, hub bores include 78.1mm, 87.1mm, 106mm, and 124.9mm, and bolt patterns span several vehicle families.
That makes compatibility more important than choosing by appearance or thickness alone. Compare your vehicle’s specifications with each listing, including whether it requires factory wheels or extended lugs, before selecting a spacer.
The ranking prioritizes stated fitment, useful specifications, and included hardware.
KSP 6×5.5 Silverado Spacers is the strongest overall choice in this group for compatible Silverado and Sierra owners: it lists a 6×139.7 pattern, 78.1mm hub bore, M14x1.5 studs, and 1.5-inch thickness. Its listing also specifies forged 6061-T6 aluminum and includes four spacers. Buyers with a different vehicle or a preference for a thinner spacer should compare the other ranked options carefully; bolt pattern, hub bore, and thread pitch must match their exact setup.

Detailed Reviews: Best Hub Centric Wheel Spacers
Why it ranks #1: Lists 1.5-inch thickness, 6×139.7 pattern, 78.1mm hub bore, and M14x1.5 studs for many Silverado and Sierra applications; forged 6061-T6 construction.
Forged 6061-T6 aircraft aluminum is the defining feature of this KSP set, giving Silverado and Sierra owners a 1.5-inch spacer option made from a material the listing describes as more durable than cast aluminum. Its 78.1mm hub bore and M14x1.5 studs specify the interface for listed GM applications.
CNC precision machining and accurate hole positioning are intended to help the spacer align consistently during installation, while the 6×139.7 bolt pattern and 78.1mm hub bore identify its wheel and vehicle interfaces. The 1.5-inch thickness provides a substantial track-width change for listed trucks and SUVs. The four-piece set covers a broad range of Silverado, Sierra, Tahoe, Yukon, Suburban, and other named GM applications, so checking the specific model and year against that list is essential.
- Forged 6061-T6 aircraft aluminum construction
- CNC precision machining with accurate hole positioning
- 1.5-inch thickness with 78.1mm hub bore
- Four spacers included for listed GM applications
- The 1.5-inch thickness makes this a substantial spacing change, not a subtle adjustment.
Skip it if you want only a small spacing change; the listed 1.5-inch thickness is substantial, while Wheel Accessories Parts' 15mm Silverado/Sierra kit is thinner.
GM truck and SUV owners seeking a forged 1.5-inch spacer set can consider this KSP option. Its listed fitment spans many model years, but the 78.1mm bore and vehicle-specific application list remain important fit considerations.

#2 · Broad GM Fitment
2. dynofit 1.5-inch Silverado Spacers
- Weight: 19.58 lb
Best for: Wide-Range GM Fitment.
Why it ranks #2: Offers 1.5-inch thickness, 6×139.7 pattern, 78.1mm bore, and M14x1.5 thread across a broad listed range of Chevrolet and GMC vehicles.
A 1.5-inch thickness paired with a 78.1mm hub bore makes this dynofit set a clearly specified option for many Silverado and Sierra 1500 applications. Its 6×139.7 pattern and M14x1.5 thread pitch provide key interface details, while the listed fitment also names Tahoe, Yukon, and other GM vehicles.
The four-piece set matches the listed 6×5.5 bolt pattern and 78.1mm hub bore, helping buyers compare the spacer interfaces with their vehicle and wheels before installation. Its 1.5-inch thickness creates a substantial change in axle spacing, so the seller's warning to keep wheels and tires within legal width limits matters when assessing the finished setup. The broad year and model list is useful, but local regulations and exact vehicle fit remain part of the decision.
- Four spacers included
- 1.5-inch thickness per spacer
- 78.1mm hub bore and 6×139.7 pattern
- M14x1.5 thread pitch
- The seller warns that the widened setup must remain within legal vehicle-width limits.
Skip it if you need a thinner spacer; this set is 1.5 inches thick, while Wheel Accessories Parts' Silverado/Sierra kit is 15mm.
This suits GM truck and SUV owners whose model and year appear in dynofit's extensive list and who want a 1.5-inch spacer. Consider the resulting overall width and local regulations before choosing this substantial spacing change.

#3 · Lugs Included
3. Wheel Accessories Parts 15mm Spacers
- Weight: 4.09 lb
Best for: Factory-Wheel Silverado Spacer Kit.
Why it ranks #3: Its 15mm, 78.10mm-bore spacers fit specified Silverado and Sierra 1500 applications, and the kit includes 12 M14x1.5 extended-thread lug nuts.
The included 12 extended-thread M14x1.5 lug nuts distinguish this 15mm kit, giving Silverado and Sierra 1500 owners the longer-thread hardware specified for proper engagement with original wheel studs. Its 78.10mm hub dimensions and 6×139.7 pattern define the listed vehicle and wheel interface.
This two-spacer kit is explicitly limited to factory wheels, so it suits buyers retaining their original wheel setup rather than changing wheel types. The 15mm thickness adds a modest amount of spacing, and the 78.10mm vehicle hub dimension corresponds to the stated hub size. Since the manufacturer calls for extended-thread lugs and includes 12 ET lug nuts, the kit supplies the specified hardware for the two spacers; validate vehicle fitment before installation.
- 15mm spacer thickness
- 78.10mm vehicle hub dimension
- 6×139.7 bolt pattern
- Includes 12 M14x1.5 extended-thread lug nuts
- The listing explicitly limits these spacers to factory wheels.
Skip it if you plan to use aftermarket wheels; this kit specifies factory wheels only, while KSP Performance's forged GM spacers are not stated as factory-wheel-only.
Choose this kit if you have a listed Silverado or Sierra 1500, intend to retain factory wheels, and want 15mm spacers with ET nuts included. The factory-wheel restriction is the key boundary to consider.

#4 · Thinner GM Option
4. Richeer 1.25-inch Spacers
- Weight: 18.39 lb
Best for: Moderate GM Truck Spacing.
Why it ranks #4: Provides a 1.25-inch option with 6×139.7 patterns, 78.1mm bore, and 14×1.5 thread for numerous listed Silverado, Sierra, Tahoe, and related models.
At 1.25 inches thick, these Richeer spacers offer a more moderate spacing change for the listed Silverado and Sierra 1500 applications than a two-inch spacer. The four-piece set pairs 6×139.7 vehicle and wheel patterns with a 78.1mm hub bore and 14×1.5 thread specification.
The matching 6×5.5 bolt patterns identify the spacer interfaces on both the vehicle and wheel sides, while the 78.1mm bore specifies the hub dimension. Together, those details help buyers compare the kit with the listed GM applications before installation. Its 1.25-inch thickness is the central choice for anyone seeking less spacing than a two-inch setup, and the compatibility list names numerous trucks and SUVs across specific model years.
- Four spacers included
- 1.25-inch thickness
- Matching 6×139.7 vehicle and wheel patterns
- 78.1mm hub bore and 14×1.5 thread specification
- At 1.25 inches, it provides less spacing than a two-inch spacer.
Skip it if you want a two-inch spacing change; this set is 1.25 inches thick, while Wheel Accessories Parts' Ford Super Duty spacer is 2 inches.
GM owners whose vehicle appears in Richeer's compatibility list and who prefer a 1.25-inch spacer can consider this set. Its specified years and 78.1mm hub bore are important boundaries to check against the intended application.

Forged 6061-T6 aluminum with CNC automatic processing is the key construction combination in this Nilight four-piece set. It gives owners of listed Silverado and Sierra applications a 1.5-inch spacer with a 78.1mm hub bore, 6×139.7 pattern, and M14x1.5 thread size.
The stated 6×5.5 bolt pattern and 78.1mm hub bore identify the spacer's connection dimensions, while the 1.5-inch thickness provides a substantial change in spacing. CNC processing and anodic oxidation are specified alongside the forged aluminum construction, giving buyers concrete manufacturing and surface-treatment details to weigh. Its application list covers several GM trucks and SUVs, with numerous named fitments ending in 2019; compare the exact model and year before proceeding.

Skip it if you have a Silverado or Sierra model year beyond the listed 2019 applications; KSP Performance lists some GM applications through 2026.
This Nilight set suits owners of GM models included in its application list who want forged spacers and CNC processing. Check the specific year carefully, because several of its listed truck fitments end in 2019.

6. SYKRSS 12mm Spacers
- Weight: 2.64 kg
Best for: Slim GM Spacer With Factory Bolts.
Why it ranks #6: A 12mm set for listed Silverado and Sierra fitments offers a 78.1mm bore and 6×139.7 pattern; its listing says factory bolts are used.
At 12mm thick, this SYKRSS set offers a comparatively slim spacing change for listed Silverado 1500 applications. Its 78.1mm hub-centric bore, 6×139.7 pattern, forged 6061-T6 aluminum, and 10.9-grade studs specify key fit and construction details for evaluating the four-piece kit.
The 78.1mm bore and 6×139.7 pattern identify the hub and bolt interfaces, while the 12mm thickness gives buyers a defined, relatively small spacing change. SYKRSS specifies forged aerospace-grade 6061-T6 aluminum and rust-proof 10.9-grade studs. The kit uses factory bolts, which are not included, and includes protective gloves and cleaning wire balls. Those supplied items and hardware requirements shape installation preparation; the listed compatibility names Silverado 1500 models from 2019 to 2021.
- 12mm thickness and 78.1mm hub-centric bore
- 6×139.7 pattern with M14x1.5 thread pitch

- Protective gloves and cleaning wire balls included
- Bolts are not included; installation uses the factory bolts.
Skip it if you need replacement bolts included in the kit; these use factory bolts, while Wheel Accessories Parts' 15mm kit includes extended-thread lug nuts.
Silverado 1500 owners within the listed 2019–2021 fitment seeking a 12mm spacer can consider this SYKRSS set. Account for its factory-bolt requirement and check the exact vehicle application before installation.

View on AmazonWhy it ranks #7: Provides a 1.5-inch option for listed Tacoma and 4Runner fitments with a 106mm hub bore; the listing flags extended lug nuts for some setups.
Included thread locker and guidance on extended-thread lug nuts set this KSP spacer apart for owners of listed Tacoma and 4Runner applications. The 6×139.7 bolt pattern and 106mm hub bore specify the key interfaces, while the title identifies a 1.5-inch spacer for the named Toyota fitments.
KSP advises replacing the original nuts with extended-thread nuts when the original bolt length is under 27mm, calling out Tacoma and FJ in particular. That threshold gives buyers a concrete installation check rather than leaving lug engagement unspecified. Included thread locker is intended for fastening, and the matching 6×5.5 vehicle and wheel patterns help define compatibility. Check the product's vehicle list carefully, since the listing emphasizes verifying application before purchase.
- 1.5-inch spacer thickness
- 6×139.7 vehicle and wheel bolt pattern
- 106mm hub bore
- Thread locker included, with ET nut guidance
- Original bolt length under 27mm calls for extended-thread lug nuts.
Skip it if you cannot use extended-thread nuts when your original bolts are under 27mm; dynofit's 6×135 Ford spacer serves a different vehicle fitment.
Tacoma and 4Runner owners seeking the listed 1.5-inch spacer and supplied thread locker should assess this KSP set. Check the exact vehicle application and original bolt length, since short bolts call for extended-thread nuts.

Two-inch thickness is the defining specification of this dynofit spacer set, providing a substantial axle-spacing change for the listed Ford F-150, Expedition, and Lincoln Navigator applications. The title also specifies a 6×135 bolt pattern, 87.1mm center bore, and M14x1.5 studs for comparing key fit dimensions.
The 6×135 pattern, 87.1mm center bore, and M14x1.5 stud specification give buyers several concrete interface measurements to check for the named vehicles. At two inches thick, each spacer represents a substantial spacing change, so the seller's reminder to keep wheels and tires within legal width limits is relevant to the completed setup. The stated fitment covers 2015–2026 F-150, Expedition, and Navigator models; verify the specific application and local width rules.

9. Wheel Accessories Parts 8×170 Spacers
- Weight: 28.7 lb
Best for: Ford Super Duty Single-Rear-Wheel Fit.
Why it ranks #9: Targets listed Ford F-250 and F-350 Super Duty applications with a 2-inch thickness, 8×170 pattern, 124.9mm hub dimensions, and M14x1.5 thread.
A 124.9mm hub dimension and 8×170 pattern define this two-inch Wheel Accessories Parts spacer set for listed Ford Super Duty single-rear-wheel applications. The four forged 6061-T6 aluminum spacers also specify M14x1.5 threads, giving buyers key interface details for evaluating fit.
The matching 8×170 vehicle and wheel patterns, plus 124.9mm hub dimensions on both sides, make the intended interfaces explicit for listed F-250 and F-350 Super Duty models and the named Excursion application. Forged 6061-T6 aluminum and black anodizing are specified as material and surface-treatment details; the anodizing is described as enhancing hardness and corrosion resistance. At two inches thick, the set creates a substantial spacing change, so confirm the single-rear-wheel application and resulting width.
- Four spacers, each two inches thick
- 8×170 vehicle and wheel patterns
- 124.9mm hub dimensions on both sides
- Forged 6061-T6 aluminum with black anodizing
- Fitment is specified for single-rear-wheel applications, not all Super Duty configurations.
Skip it if you have a dual-rear-wheel Super Duty; this listing specifies single-rear-wheel fitment, while dynofit's 6×135 kit is for different Ford applications.
This set is for owners of the listed Ford Excursion, F-250, or F-350 applications with single rear wheels who need the specified 8×170 interface. Confirm configuration and width suitability before choosing its two-inch thickness.

Adding two inches to the axle track is the defining effect Orion Motor Tech specifies for this 5×4.5 spacer kit. Its hub-centric design, 64.1mm center hub bore, T6 aircraft-grade aluminum construction, and included M12x1.5 bolts give buyers concrete fit and material details to assess.
The hub-centric design and 64.1mm center bore identify the intended hub interface, while the 5×4.5 pattern narrows the relevant wheel applications. Solid-block T6 aircraft-grade aluminum combines a stated lightweight material with durable construction. The kit includes 20 Dacromet-coated M12x1.5 bolts, which the listing describes as seven to ten times more corrosion resistant than the competition. Its two-inch axle-track addition is substantial, making fit and intended width important considerations.

View on AmazonAvoiding Hub-Bore and Wheel-Fitment Mismatches
A matching bolt pattern alone does not establish that a spacer is hub-centric for your vehicle and wheel. Several Silverado-oriented products list a 78.1mm bore, while the KSP Tacoma 1.5-inch Spacers list 106mm and the dynofit Ford 2-inch Spacers list 87.1mm. The Wheel Accessories Parts 8×170 Spacers specify 124.9mm hub dimensions, and Orion Motor Tech 5×4.5 Spacers list a 64.1mm center bore.
These values are not interchangeable. Also verify both sides of the fit: the spacer must match the vehicle hub, and the wheel must fit the spacer’s wheel-side hub or opening.
Product listings may cover broad model-year ranges, so confirm the exact vehicle trim and wheel configuration with the seller or a reliable fitment lookup before ordering. A pattern or bore mismatch can prevent proper seating, even when the product name appears to match.
Lug Engagement Is a Separate Compatibility Check
A spacer can match the hub and bolt pattern yet still require different lug hardware or careful installation. Wheel Accessories Parts 15mm Spacers explicitly say they fit factory wheels only and include extended-thread lug nuts, while the KSP Tacoma 1.5-inch Spacers advise extended lug nuts if original bolt length is under 27mm. By contrast, SYKRSS 12mm Spacers say factory bolts are used and that bolts are not included.
These details make it important to check the hardware instructions for the specific product rather than assuming every spacer installs the same way. Thread pitch also matters: many Chevrolet and GMC options list M14x1.5, while Orion Motor Tech 5×4.5 Spacers list M12x1.5 bolts.
Follow the product’s installation guidance and use appropriate tools; SYKRSS specifically cautions against over-tightening with power tools. If unsure, have a qualified installer verify engagement and torque.
How to Choose Hub-Centric Wheel Spacers
Vehicle and Wheel Fitment
Start by matching the vehicle and wheel bolt patterns, then verify the hub bore rather than relying on a broad model list. Several Silverado and Sierra options specify 6×139.7 and 78.1mm, but the KSP Tacoma 1.5-inch Spacers specify a 106mm bore, the dynofit Ford 2-inch Spacers specify 6×135 and 87.1mm, and the Wheel Accessories Parts 8×170 Spacers specify 124.9mm. For a compatible GM truck, the 78.1mm choices provide several thickness options; for a listed Ford or Toyota fitment, choose a product with its matching pattern and bore.
Confirm the exact model, year, trim, and wheel before purchase.
Spacer Thickness
Choose thickness according to the amount of added track you intend, while checking wheel clearance and the vehicle’s legal width limits. The listings range from SYKRSS 12mm Spacers and Wheel Accessories Parts 15mm Spacers to Richeer 1.25-inch Spacers, multiple 1.5-inch choices, and 2-inch options from dynofit and Wheel Accessories Parts. The thinner choices suit buyers seeking a smaller change, while the 1.5- and 2-inch products represent larger listed thicknesses.
Thickness alone does not establish clearance: wheel offset, tire size, suspension, and fender space also matter, and those details are not established for every vehicle in the product data. Check your setup before selecting a wider spacer.
Included and Required Lug Hardware
Check whether the kit includes hardware and whether your vehicle needs extended lugs or factory bolts. Wheel Accessories Parts 15mm Spacers include 12 M14x1.5 extended-thread lug nuts, while KSP Tacoma 1.5-inch Spacers flag extended nuts when original bolt length is under 27mm. SYKRSS 12mm Spacers say bolts are not included and factory bolts are used.
Thread sizes vary too: many GM products list M14x1.5, whereas Orion Motor Tech 5×4.5 Spacers list M12x1.5 bolts. Buyers wanting listed lug nuts included should consider the Wheel Accessories Parts 15mm kit, while buyers whose setup uses factory bolts should verify the SYKRSS instructions and fitment.
Never assume hardware transfers between vehicles.
Which Hub-Centric Wheel Spacers Should You Choose?
For a compatible Silverado or Sierra that needs a 1.5-inch spacer, choose KSP 6×5.5 Silverado Spacers: it combines a 6×139.7 pattern, 78.1mm bore, M14x1.5 studs, and forged 6061-T6 construction. For similar GM fitment with a thinner change, compare Richeer 1.25-inch Spacers or Wheel Accessories Parts 15mm Spacers; the latter includes extended-thread lug nuts and specifies factory wheels only. Choose SYKRSS 12mm Spacers if its listed fitment matches and you want the thinnest option here.
Toyota buyers should examine KSP Tacoma 1.5-inch Spacers and its lug-length note. Ford shoppers should match their exact pattern to dynofit Ford 2-inch Spacers or Wheel Accessories Parts 8×170 Spacers.
Orion Motor Tech 5×4.5 Spacers serve a different pattern. Confirm full fitment before ordering.

Match the spacer’s bolt pattern and hub bore to your vehicle, then confirm the wheel-side pattern and centering fit your wheels. Check the exact vehicle configuration and wheel specifications rather than relying on a broad make or model description. Also verify stud thread pitch and spacer thickness before ordering.
Do wheel spacers require longer or extended lug nuts on my vehicle?
It depends on the spacer design and your vehicle’s available thread engagement. Check the product’s included-hardware details and fitment notes; the Tacoma listing, for example, mentions an extended lug nut, while one 15mm listing includes lug nuts. Confirm the required nut type and engagement for your exact setup before installation.
Can wheel spacers cause tire rubbing or affect vehicle legality?
They can change wheel position, so rubbing may occur depending on the vehicle, wheel, tire, and spacer thickness. Check clearance through the steering and suspension range after fitment. Legality varies by location and vehicle; consult applicable local rules and a qualified installer before using spacers on public roads.
How should I choose spacer thickness?
Choose the thickness that meets your fitment goal while preserving clearance at the fenders, suspension, and other components. This group includes options from 12mm to 2 inches, but those sizes are not interchangeable. Confirm the correct thickness for your vehicle and wheel combination rather than choosing by appearance alone.
What should I check before installing wheel spacers?
Verify the spacer’s vehicle fitment, bolt pattern, hub bore, thread pitch, thickness, and required lug hardware against your exact setup. Inspect that mating surfaces are clean and that the wheel seats correctly. Have a qualified installer follow the vehicle maker’s procedures and torque specifications, then recheck fitment as recommended.
Final Words
For compatible Silverado or Sierra owners needing a 1.5-inch spacer, the KSP option is the strongest overall pick in this group, with listed 6×139.7 fitment, a 78.1mm bore, M14x1.5 studs, and forged 6061-T6 construction. For a thinner GM change, compare the Richeer 1.25-inch and Wheel Accessories Parts 15mm options; Toyota and Ford owners should check their dedicated listings. Confirm exact fitment and hardware before ordering.
